GSC — Oryza sativa Indica Group

Summary

BGIOSGA016558 (GSC) on Indica rice chromosome 4 encodes a fructose-bisphosphate aldolase (EC 4.1.2.13) with an aldolase TIM barrel domain, catalysing the reversible conversion of fructose 1,6-bisphosphate into dihydroxyacetone phosphate and glyceraldehyde 3-phosphate in cytosolic glycolysis and the Calvin cycle. The gene is associated with glycolytic and gluconeogenic processes, aerobic respiration, redox and anoxia responses, sucrose metabolism, seed germination regulation, and fruit development. It has been linked to traits including seedling growth, root thickness, stomatal closure, salt and oxidative stress tolerance, disease tolerance, and germinability at low temperature. Localisation evidence connects the product to the mitochondrial envelope, chloroplast thylakoid, and vacuole. Studies of related genes in other species associate the family with drought tolerance, heat stress response, and seed size.
